That explains it, thank you. I guess the reason for not using GPS or other instruments for ground speed is also legislation?

- travisjungroth 4y agoThat one doesn't make any sense to me. The helicopter would certainly have ground speed via GPS. I don't get how you couldn't use that. A car can use its speedometer. I remember seeing a laser pod on the wing of a CHP airplane and talking to them about it, but it was a long time ago and I couldn't confirm it more than finding pictures that show the pod (but maybe it's a camera). Based on my experiences involving journalism and aviation, it is extremely possible that the author incorrectly described what the pilot was doing.
